' 'furnacesi issues from the tip in a conical form resulting, with oil fuel, in what is known as a round flame. Iam also aware that sprayingv devices have been used in which an atome izing or spraying medium, such as compressed air or steam, ,is employed `to spray the liquid, and that such devices have pros ducefd'a spray issuing vfrom the tip in a sin-l4 gle 'plane resulting in a flat oifantail` formof spray, or what is known in the case of liquid fuel asa flat llame. There are manyinstances Where the flat flame is best adapted to the local conditions existing in a s fumant! giving a more uniform distribution Iof heat and better' eliiciency. -There are, in

fa'ct conditions in which a round flame buri er cannot be used to give the desired results, andthe superiority ofthe flat flame burners: has resulted in the entire aban. donment vof the round flame burners in certain, localities and in vcertain forms of On the other hand, therel are `many instances in which oil is used as a fuelwhermthe localconditions practically prohibit theluse of atomizers in which an atomizingiedinmuch as compressed air or steam is employed. This is true particularly 'i in connection with marinework where steam tionable compressing machinery and the use l cannot be used on. account?A of 'the 1oss,of

freshwater aid where compressed air necessitates the installation of heavy and objecof large and unwieldy pipes'throughout the 1 boiler, room; In installations of this charac ter the vclass of oil burners in which oil is SPlaVffd lr-'fmd bv means of a whirling motion imparted 'to the oil by means of pressure has practically supplanted all other types', and it is to a device ofthis character thatthe present invention is directed. In the present device, however, the liquid is atomized or sprayed without the use of compressed air or steam, thereby obtaining 'the advantages of the flat flame without the 0bjectionable features incident to the 'employ ment of' compressed air or steam.

Vhile I ha ve described the passages' as tangential to the wall of the washer 6 and the wall of the chamber 10, I desire t0 include within said term any degree'of eccentricity of said passages-which will give to the liquid a rapid whirling motion. vWhat I claim and desire to secure by Letters Patent of the United States is l. In a spraying device for liquids, a. nozzle having a chamber, and means for `introducing a stream of liquid into said chamber tangentially thereof without the use of air ,or steam to produce a rotary movement of .the liquid, said nozzle having.. a discharge4 slot through which the liquid is discharged in a single plane; substantially as described.

2. In a spraying device for liquids, a -nozzle having a chamber, and means forintroducing a stream of liquid into said chamber tangentially thereof without the use of air or steam'to produce arotary movement of the liquid, said nozzle having a dischar opening in a direction at substantially rig t p angles vto the axis of said chamber, whereby the liquid is discharged through said 'opening in a single plane substantlelly parallel to the plane of rotation in SadchambeI. v

In testimony whereof I have hereunto signed my name in the presence oftwo'sub-v scribmg witnesses.
